Abstract
The present pertains to the field of chemical industry, wherein an antisludging agent for industrial circulating water systems is disclosed, which comprises thiocarbamide, benzotrizaole, mercaptobenzothiazole, sodium silicate and water. The antisludging agent has good inhibiting effects to various acids and metals.
Description
Technical field
The invention belongs to chemical field, relate to a kind of chemical inhibiter, more specifically, the present invention relates to a kind of inhibiter that is used for industrial cooling circulating water system.
Background technology
In order to prolong industrial equipments, to make work-ing life of large-scale industrial equipments especially, need carry out inhibition to industrial cooling circulating water system usually and handle.At present, the main acid restrainer that uses comes the industrial cooling circulating water system before cleaning is carried out inhibition in the prior art, though the acid attack agent of prior art has corrosion mitigating effect preferably, but most of effective inhibiter all has specificity to a certain extent, and effect is not ideal when usually multiple metal being carried out inhibition.But the system that is cleaned often is made up of multiple metal, and is improper if inhibiter is selected for use, and its consequence is hardly imaginable, even makes whole industrial equipments paralysis.
At above shortcoming, the inventor develops a kind of inhibiter of being made up of polycomponent, and it can have rust inhibition at multiple acid, many clocks metal, and corrosion inhibition rate is effective.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of inhibiter that is used for industrial cooling circulating water system, and the prescription that the present invention adopts is by weight percentage: thiocarbamide 15～20, benzotriazole 8～20, mercaptobenzothiazole 5～10, water glass 10～20, water 35～55.
Further, be about 3-8 hour the action time of inhibiter of the present invention.
Further, the operative temperature of inhibiter of the present invention is 20-50 ℃.
Product of the present invention is the inhibiter that uses before a kind of pickling, can be applied in the multiple clean-out system media such as hydrochloric acid, nitric acid, EDTA, citric acid, but also be multiple metal material good inhibiter in the clean-out system medium.
Inhibiter of the present invention is specially adapted to the industrial colling recycle system, and its action time is short but effect is preferable.Operative temperature of the present invention is 20-50 ℃, has wide temperature range, and this temperature range comprised ambient temperature substantially, has therefore simplified working conditions, and has not influenced follow-up cleaning performance.
Embodiment
Embodiment 1 using method that is used for the inhibiter of industrial cooling circulating water system of the present invention
1, system is clean with flushing with clean water, and the ON cycle water pump is guaranteed the unobstructed no water clock of the recycle system.
2, add this product from expansion tank or chemicals dosing plant or unlimited pond etc., concentration is controlled at about 2%.
3, continued the ON cycle water pump at least 1 hour, guarantee that inhibiter concentration in total system is even.
4, handling about 5 hours, can add the clean-out system that is used for industrial cooling circulating water system, carry out follow-up cleaning through inhibiter.
Claims (3)
1. an inhibiter that is used for industrial cooling circulating water system is characterized in that, the prescription of employing is by weight percentage:
